APPARATUS FOR THE PREPARATION OF TEXTILE THREADS Leib Windschauer, Berlin, Germany; vested in the Alien Property Custodian Application April 30, 1942, Serial No. 441,151

In Germany March 10, 1938 3 Claims.

The invention relates to suitable devices for preparing textile threads in the running thread for manufacture on weaving machines, hosiery machines and looms. The thread is passed through a treating agent containedin a vessel provided with lateral inlet openings and outlet openings.

It is known to grease threads with liquid greasing agents and also with solid agents, made up of pieces, such as parafilne or wax. .When using liquid agents it is difiicult to seal or pack the inlets and outlets of the thread; when using solid agents the pressure between the solid pieces results in partly gripping the thread. In such case the greasing will not be uniform, and there is considerable likelihood of breaking the thread.

According to the present invention, however, the thread is passed through a highly-consistent grease mass subjected to pressure in a vessel provided with lateral inlet and outlet slots. This permits inserting sensitive and easily breakable threads, since they cannot be gripped in the consistent grease mass. It will be possible to impart great rapidity to the passing of the thread, as the formation of a tunnel surrounding the path of of the pressure,'as would be the case with a liquid subjected to pressure. The threads can be easily inserted through the slots and the pressure piston, serving for generating the pressure, when passin downwards corresponding to the consumption of the grease mass, is not hindered by the thread as this can follow in the slot, being always imbedded in the grease mass.

For collecting the grease particles escaping through the slots with the thread from the vessel, there are arranged on the vessel containing the treating agent outside of the walls provided with the thread passing slots, one or more separating chambers for the. treating agent.

In addition, in order to prevent the formation of tunnels in the case of a very high rate of pass ing speed of the thread, provision may be made by the design of the vessel to have the pressure directed in radial direction towards the path of the thread. The bottom of the vessel and the under surface of the pressure piston may be corruated in the direction of the run .of the thread. This also causes continual follow-up pressing of the grease mass into the path of the thread.

The pressure acting on the grease mass may be exerted, in addition to usinga movable coverin piston, also indirectly over the grease mass itself or by a transmitting agent, for instance, compressed air, pressure gas or a pressure liquid. In order to permit uninterrupted treatment of the thread, the total arrangement may be designed in such a manner that several of the passage spaces for the threads containing the grease mass are connected over a common collective lead to several storage vessels subjected to pressure which may be individually separated from the collective lead. By alternately re-filling one of the storage vessels, at the time, which has been previously separated from the collective lead, it will be possible to continually keep the plant under pressure by way of the other storage vessel.

The drawings show several modes of construction of the arrangement for making use of the invention.

Figure 1 shows a longitudinal section through a grease vessel with an elastic pressure piston.

Figure 2 shows a side view thereof.

Figures 3 and 4 show two-differing modified forms of, a cross section of the design of the vessel. Figures 5 and 6 show two differing modified modes of construction in longitudinal section.

Figure 7 shows a mode of construction of the pressure piston with thread holders in perspective view.

- Figures 8 and 9 show a total arrangement with collective lead and storage vessels subjected to gaspressure in side elevation and plan view.

In the arrangement of the Figures 1 and 2 the thread I passes first over the roll 2 pressed upwards by spring action and through the prechamber 3, whose walls 4 and 5 are provided with slots 6 and enters the grease mass 1, which is subjected to the pressure of the slidablepiston 8 which is pressed downwards by a spring 9 with regulable counter plate III. The thread is led out through the slots, in the walls I I and I2, through the separating chamber l3 and through the afterarranged stripping chamber M, which may be filled with felt, over the roll [5 to the reel or the skein winder. The spring 9 is supported, for ensuring as uniform spring power as possible, over the entire length of its path by a comparatively high pair of stays [6 with the aid of the retractable cross piece H and the adjusting screw it. The part of the vessel containing the grease mass arranged between the walls 5 and H. may-have simple rectangular side walls H! as shown by Figure 2. But the walls may also be so designed that the efiect of the pressureof the piston 8 may be reflected, as it were, towards the thread I. This results, for instance, from the mode of construction of Figure 3 by the downwards tapering walls and still more so as shown by Figure 4 by the walls 2| being bent upwards at both sides at the bottom. For further augmenting this effect the piston 8, according to Figure 4, is provided with lateral projections 22, which exert an especially large amount of the total pressure on the zones of the grease mass located at the walls and in their vicinity.

In the arrangement shown in Figure 5 the bottom 23 of the passage vessel and also the pressure piston 24 is corrugated in the direction of the run of the passage of the thread i, so that the path of the grease particles carried along by the thread extends obliquely to the path of the thread roper.

In the mode of construction shown by Figure 6 the corrugations of the bottom and the piston will be increasingly curved during the length of path and will follow one another in quicker succession.

On the piston 8 shown in Figure 7 are provided hooks guiding the thread on an angular path. Angularity in the direction ofthe path of the piston may be obtained by difiering lengths of the hooks 25.

In the arrangement according to Figures 8 and 9 several vessels 26, closed at the top, are connected over heavy leads 27 to a common collective lead 28 from which they may be individually disconnected by a slide 29. To the same collective lead 28 are connected the storage vessels 30 and 30', which may be disconnected by the slide 3! and by way of the leads 32 may be subjected to the pressure of a liquid or a gaseous medium.

The lead according to the Figures 8 and 9 per-- from the collective lead 28 by its slide 3| and 3|, respectively, and the other storage vessel or storage vessels keep the total arrangement under pressure during this time. The vessels 26 may be made in one of the modes of construction of the Figures 1 to '7; the cover of the vessel, however, need not be movable in this case but may be firmly and tightly connected to the walls of the vessels.

What is claimed is:

1. An apparatus for the treatment of textile threads comprising a vessel having opposed slots extending substantially the height of its end walls and open at their upper ends, through which the threads extend, said vessel being designed to contain a grease mass too viscous to flow out of said slots, means for supplying pressure to said mass in a direction transversely of the path of the threads through the vessel to prevent channeling of the grease mass, and chambers provided at each end of the vessel to collect any grease exuding through the slots.

2. An apparatus for the treatment of textile threads comprising a vessel having opposed slots extending substantially the height of its end walls and open at their upper ends, through which the threads extend, said vessel being designed to contain a grease mass too viscous to flow out of said slots, and means for supplying pressure to said mass in a direction transversely of the path of the threads through the vessel to prevent channeling of the grease mass, said means comprising a spring-pressed piston movable transversely relative to the path of the threads.

3. The apparatus of claim 2 wherein said piston and the bottom of the vessel opposed thereto are provided with corrugations running in a direction to oppose the movement of the grease with the threads.
